After a love affair full of gaslighting comes to an end, Soojin is haunted by the green-lit girl she slept with in a drunken stupor the night before. Her body was glowing; she literally emitted green light. Soojin’s friends scold her for losing her mind, but suddenly a UFO appears in the sky of Seoul and starts attacking everyone. Will Soojin be able to find the green girl in the middle of hell? The latest alien-invading sci-fi action-romance blockbuster from Jung Inhyuk, who has created his own genre by mixing minority stories with B-grade humor and clichés.
